Classification of rocks according to Faults
Vertical, horizontal or slanting cracks can be used for climbing. Depending on their width one can use an appropriate technique for climbing. A wider crack in which a climber can enter is called as chimney. If the crack is wider than a chimney then it is called as a gully. A corner is formed where two rock walls meet each other at about 90 degrees. A groove is formed by two narrow rock walls meeting each other at an angle.If the angle is more than 90 degrees then it is called as Shallow groove and it is less then it is called as Vee groove. A small blunt and narrow ridge protruding out of the rock is called as Rib. A much sharper projection than the rib called as arete. A position on the rock wall where a climber can comfortably stand or sit is called a stance. A ledge is comparatively a wider stance where a group of 2-3 climbers can sit or stand during a climbing activity.
Types of rock climbing
Rock climbing Bouldering: This is the purest form of climbing and requires the least amount of gear.
Sport climbing
Peak bagging
Free soloing: This is climbing without a rope but this is one of the dangerous aspects as there is no room for error.
Expedition climbing: There are no rules here. You can use any kind of gear to get up. Probably the most expensive form of climbing.
Crag climbing: Multipitch rock climbing at its best.
Wall climbing: Wall climbing uses aid climbing gear to directly support your weight on a wall. This is the opposite of "free" climbing where gear is only used in the event of. Mixed aid and free climbing are call "mixed climbing."
Alpinism: A blend of rock and snow/ice climbing. Very few climbers come in this category.
